CASE Fo THE PRESERVATION-OF Bo;oK's.,l

SPECIFICATION forming part of Letters Patent No. 381,1s2, datea April 17, 1888. Application filed ctober5,1887. Serial No. 251.544. (No model.) A 7 To all whom it may concern.-

Be it known that I, CHARLES DUDLEY THRELKELI), a citizen of the United States, residing at Benton, in the county of Franklin I and State of Illinois, have invented a new and useful Improvement in Cases for the Preservation of Books, of ;which the following is a specification.

My invention relates to an improvement to in combined book protectors and supports;

and it consists in the construction and ar rangeinent of the parts-thereof, which will be 1 more fully hereinafter described, and pointed out in the claims. p

The object of my invention is to construct a case which will preserve bound or unbound p books contained therein, and, .when desired to be used for a support therefor, whereby a convenient device is provided for use by chil- 2o dren and elder people. y

.In the accompanyingv drawings, wherein like letters of reference indicate similar parts in the several views, Figure 1 is a perspective view of my improvement shown closed. Fig. 2 5 2 is a similar view with thedevice open and the book supported thereby. Fig.3 is a view w theinner upper side of the. door A with --a lock, A. The door'A hastwoleaves, B B, hinged to the oppositesi'des thereof in grooves b so that they may be laid down, and a'rear standard, B, having'alug, b, atits lower portion provided with an aperture, b, through which passes oneend of a cord, 0, which is secured to thestandard. This cord 0 is passed throughthe book and secured in a staple or eye, a, mounted adjacent to thelock at its other end, and thereby holds the book to the 7 door. The leaves B B fold up against the sides of the book, and thereby preserve the same when folded withinthe box, and form restswhen open for the open book.

Suitable brace-straps, B, are secured to the rear of the leavesB and tothe standard B to the case, as :will be readily understood.-

limit the downward movement of said. leaves and formthe proper support for the book= covers. M 1

To the inner upper portion of the standard 5 Ba staple, b, is secured, through which an elastic connection, D, is vpassed, the ends thereof being secured to the inner surface .of one of theends of the case A. Bythis means the door A carrying the book, is drawninto The upper rear portion of the case is formed with a keyhole slot, a, to be engaged by a nail or hook for supporting the case in a suspended position. V I e If so desired, the, drop-door A may be provided with clamps to aid insecuring the book thereon; but these clampsform no part of my invention, and I have not illustrated them. j

My'improvement is adapted for rendering convenient the use of books for feeble persons and children without lifting the weight thereof. v

- The utility of my device being obviously. apparent, it is unnecessary to further enlargev upon the same herein.

It is obvious that when the drop-dooris' opened or swung outward and downward'the loaves will be brought out from the case also, and will automatically fall into the proper position to support the book. The standard I alsowill be simultaneously swung upward,

. thereby expelling the book from the case. In

returning the book to the. case the work is 1 facilitated by the elastic connection D.' 8 5 Having thus described my invention,whatI claim as new isw 1. The combination'of the case proper, the drop-doorhinged to said case, theleaves hinged 1 to said drop-door, the standard erected at the 0 rear of the drop-door and provided witha staple, and the flexible connection between the same and the'side of the box, substantially'as.
